Title
(EN) HEATED FLUID CONTROL VALVES
(FR) VANNES REGULATRICES POUR FLUIDES, CHAUFFEES
Abstract
(EN)
A heated fluid control valve (10) comprises fluid inlet and outlet passages separated by a metallic flapper plate (12) disposed in the fluid passageway and mounted on, and in thermal contact with, an elongated, rotatable metallic shaft (16) that passes laterally through the fluid passageway (14). The shaft (16) comprises an electrical heater (44) and a thermocouple (48) having electrical wire connections accessed through an external end of the rotatable shaft (16).
(FR)
Une vanne régulatrice chauffée (10) pour fluides comprend un passage d'entrée et un passage de sortie pour le fluide, séparés par un papillon métallique (12) disposé dans le passage à fluide et monté sur un arbre métallique rotatif allongé (16) en étant en contact thermique avec celui-ci. Cet arbre (16) traverse latéralement le passage à fluide (14). L'arbre (16) comporte un élément chauffant électrique (44) et un thermocouple (48) ayant des connexions pour fils électriques, auxquelles on accède par une extrémité externe de l'arbre rotatif (16).
